KBACKUP is intended for handling of backups no
matter whether they reside on disk or tape or even
in files. As most other backup programs available
today are either confusing the user with lots of
long command line options, or user friendly but not
powerful at all, the aim behind writing KBACKUP was
to provide a user friendly yet powerful backup
program. It is also intended to be kept compatible
to existing and well proven archive formats, so you
can restore your archives even if you should not
have KBACKUP around anymore.

CodeBase is a high-speed xBASE compatible database engine for C/C++, Visual Basic, Delphi & Java programmers.
